2 Claims.

My invention relates to the handling of sheet metal being out on any type of reciprocating knife shear, and has three specic objectives which are as follows:

, 1 First: To `entirely eliminate the mixing of the scrap metal with the metal sheets, strip or blanks being cut on the shear.`

Second: To provide a means of piling the sheared sheets, strips or blanks with the scrap dangerous hand piling, and separating of the Y out material from the scrap material.

reducing the cost of shearing metal.`

The accomplishment of these objectives will be` apparent to oneskilled in the art. For a better understanding of my invention, I now refer you to the drawing, in which like characters indicate like parts throughout the several views.

Fig. 1 is a plan view of a typical reciprocating knife shear, with the various parts and features of my invention added.

Fig. 2 is a section view on line 2-2 of Fig. 1.

Figs. 3, 45, 6 and 7 are views of the remaining, several parts of the device which will be eX- plained in detail in the assembly and operation explanation which follows: Referring to the drawing, Fig.` 2, shows the material slide`3 in place with adjustable plate I adjusted to the entirely closed position. Fig. l, shows a cut `section of the adjustable plate I in the entirely closed position, variations in the size .V of gap can be made by moving the adjustable plate I, on which there areA two fixed pins I3 into either of the holes I4. Taking the adjustable plate, I, away entirely will provide the maximum amount of gap 2Yrequired for any job being cut as shown (Figs. l, 2). This variable gap provides the means of separating the scrap material from the materialbeing cut to size.

Obviously, a narrow trim cut from a'sheet of materialwill fall of its own weight into this gap 2 provided for that purpose, the material being cut to size being of a much wider dimension will overlap the gap and continue on down the slide I. i

A pit or receptacle may be provided to receive the scrap material which drops through this gap. Construction of the receiving rack is as follows: The rail l :forms the base of the rack,` all other metal thus separated, thereby eliminating the,

ciiiciently function as specified, thereby greatly.

` parts of the rack are related to it in one way or another as will be shown in the construction explanation following. l

The pin 5 being faced with wood I5 to prevent damage to the material when it comes into contact with it, is the stop or bumper pin and slips into hole 6 and held in place by lug 5'. The pin 'l slips into hole 8 nearest to, but not less than,

the width of strips to` be cut, thus providing the receiving pocket for the sheared material. Two or more of these rail assemblies formed by means of pins 5 and l and rail 4 will be needed to form the rack accordingto the lengthy of material being cut, and can be spaced and keyed into position by means of pins I which slip into Aholes II as selected. Pins Illhaving been slipped into the selected holes II being of suicient length will protrude above the level of the floor, thus providing the keys to ho-ld the rail assemblies in the locations selected, by means of holes 9 in the bottom of rail (Fig. 4) which will accommodate the protruding pin or key as shown Fig. 2.

Fig. shows a View of pin 'I having three spacers I2 telescoped over it whichwill be found very effective in procuring the desired spacing between pin 5 and pin 'I when necessary.

Having thus described the objectives and the construction of my invention, I claim as new and useful and desire to protect by Letters Patent the following:

1. A stacking device for a shear comprising, rail means, provided with a hole having a keyway, bufferv pin `means having key means removably secured to said rail means, the said rail means, further provided with a multiplicity of holes, and spacer pin means removably secured to said stacking device by virtue of said holes, thesaid stacking device adapted to receive and stack sheared material thru gravitational action.

2. A stacking device for a shear comprising, rail means providedwith a hole having a keyway, buffer pin means provided with key means removably secured to said rail means, the said rail means further provided with a multiplicity of holes, spacer pin means removably secured i to said rail means by virtue of said holes, and sleeve means telescopically and removably secured to said spacer pin means, the said stacking device adapted to receive and stack sheared materia] thru gravitational action.
